A study found that taking just two doses of the HPV vaccine may be as effective at preventing cervical cancer as taking the recommended three doses. It's great news, since plenty of people aren't getting all three shots anyway.

According toUSA Today, the finding is the result of an analysis of data from the National Cancer Institute's Costa Rica Vaccine Trial. The 7,466 women enrolled in the study were given either the HPV vaccine Cervarix, or a Hepatitis A vaccine.

Plus, for American parents who aren't dissuaded by the (made-up) possibility that vaccinating their daughter will turn her into a wanton slut, only having to see the doctor for two of the sometimes-pricy shots may encourage them to get the vaccination.
